Minimally invasive femoral stem EXACTA RS

cementless

EXACTA RS combines a unique triple tapered design with a double plasma spray coating HaX-Pore® in the mataphyseal region (300 µm pure Titanium and 50 µm HA applied with plasma spray technique) in order optimize primary stability and osseintegration. Design The triple tapered design (frontal, coronal and sagittal) supports axial and rotational stability favouring load distribution in the metaphyseal region. The progressive growth of the neck proportional to the stem size allows for a better restoration of the natural anatomy. The anatomical curvature and the optimized dimensions allow an easy introduction even with minimally invasive techniques or with anterior approach, as well as a limited bone sacrifice. Standard e Lateral 12 sizes STANDARD and LATERAL Taper 12/14 (top angle 5°42’30”) BIOLOX approved. Neck Reduced section to optimize ROM. Mirror polished finishing to minimize wear on UHMWPE joint liner. Stability Horizontal grooves in the proximal portion for improved axial stability. Bio-active coating The HaX-Pore® double coating of porous Titanium and hydroxyaopatite applied with plasma spray technique in the metaphyseal region guarantees an optimal primary fixation and encourages osteoblast colonization thus promoting biological integration. Distal tip The tapered design and the glossy finishing avoid load concentration on the femoral cortex thus postoperative thigh pain. MATERIALS The EXACTA RS stems for cementless press-fit application are made of Titanium Aluminium Niobium forged alloy in compliance with ISO5832/11 Standards.
